'Journey to the Center of a Triangle' (1976) 8m, dir. Bruce & Katharine Cornwell. Another fabulous film by the Cornwells, created on the Tektronics 4051 Graphics Terminal. Presents a series of animated constructions that determine the center of a variety of triangles, including such centers as circumcenter, incenter, centroid and orthocenter.

Plane geometry has never looked this cool!
A truly amazing "lecture" on the four classical centers of a triangle. Done entirely without any narration or explanation, repeated examples show how to construct, apparently with a compass and straightedge, the centers set to a downright somnolent piece of music.
The final, "The Grand Tour", is a more amazing (if that's possible) animation showing the movement of these points as a triangle evolves set to a snappy classical tune.
Definitely worth watching. If you get bored, just fast forward to 7:15

Minimal and beautiful
Minimal and beautiful animation, including a gentle soundtrack. Worth watching for sure, the end section is very cool.
